Thanks for the mock-up. The way the feature slider is set up, I don't think it would be able to give it that overflow you're looking for. You may need to search for another slider plugin that can do that (there are plenty here:

For the transition period (say, when the slider is moving from left to right) the incoming slide is displayed from the side, and the outgoing one also... However, they both disappear as soon as the transition is over. Also, for the moment when the extra slides are visible the horizontal width of the entire canvas is extended. I imagine both of these bugs could be worked.

If you know which Javascript and CSS functions these are a part of, I can weed it out myself. (and post any solutions here)

I have not found another slider that offers this. I swear I have seen them all at this point.

Thanks thus far.

And another example, that is flash i think.... but still does what we want.
